READY
O
This pin is used for output of signals indicating
READY for handshaking with the host system. Either
Active High or Active Low can be selected.
10
RDYPOL
READY POLARITY
ID
This pin is used for selecting the polarity of the
READY signal.
1: Active High
0: Active Low
98
SB/SW
SYSTEM BYTE/WORD
CONFIGURATION
O
This pin is used for output of signals indicating the
system bus width.
The value of bit 5 of the internal register DLCR6 is
reversed.
Low: 8-bit data bus mode
High: 16-bit data bus mode
8
MODE1
ID
This pin is used for setting to general-purpose bus
mode.
Pin no.

LEDC
COLLISION
LED
OD These pins are used for driving the LED
indicating the occurrence of collisions
(open-drain output).
52 (PC card mode)
52 (ISA bus mode)
95 (General-purpose bus mode)
LEDL
LINK LED
OD These pins are used for driving the LED
indicating the status of the link test (open-
drain output).
These pins are placed in the link-passed
state when the link test is enabled. A Low
level is output to this pin when the link test
is disabled.
When in the power-down or shut-down
mode, these pins enter the high-
impedance state, regardless of the status
of the link test.
66(PC card mode)
66 (ISA bus mode)
93 (General-purpose bus mode)
LEDT
TRANSMIT
LED
OD These pins are used for driving the LED
indicating transmit-on status (open-drain
output).
65 (PC card mode)
73 (ISA bus mode)
65 (General-purpose bus mode)
LEDR
RECEIVE LED
OD These pins are used for driving the LED
indicating receive-on status (open-drain
output).

TWISTED
PAIR OUTPUT
O
These pins are used for output of
differential transmit signals from the built-
in 10BASE-T transceiver. Preconditioning
is performed by two output pins and
external filters.

TPIP
TPIN
TWISTED
PAIR INPUT
I
These pins are used for input of receive
signals from the twisted-pair cable.
